But in some of the cases listed above, this problem is a consequence
of something else that is wrong. Be sure to check and fix the real problem.
*** Linux: Emacs crashes when dumping itself on Mac PPC running Yellow Dog GNU/Linux.
The crashes happen inside the function Fmake_symbol; here's a typical
C backtrace printed by GDB:
0x190c0c0 in Fmake_symbol ()
(gdb) where
#0 0x190c0c0 in Fmake_symbol ()
#1 0x1942ca4 in init_obarray ()
#2 0x18b3500 in main ()
#3 0x114371c in __libc_start_main (argc=5, argv=0x7ffff5b4, envp=0x7ffff5cc,
This could happen because GCC version 2.95 and later changed the base
of the load address to 0x10000000. Emacs needs to be told about this,
but we currently cannot do that automatically, because that breaks
other versions of GNU/Linux on the MacPPC. Until we find a way to
distinguish between the Yellow Dog and the other varieties of
GNU/Linux systems on the PPC, you will have to manually uncomment the
following section near the end of the file src/m/macppc.h in the Emacs
distribution:
#if 0 /* This breaks things on PPC GNU/Linux except for Yellowdog,
even with identical GCC, as, ld. Let's take it out until we
know what's really going on here. */
/* GCC 2.95 and newer on GNU/Linux PPC changed the load address to
0x10000000. */
#if defined __linux__
#if __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ >= 95)
#define DATA_SEG_BITS 0x10000000
#endif
#endif
#endif /* 0 */
Remove the "#if 0" and "#endif" directives which surround this, save
the file, and then reconfigure and rebuild Emacs. The dumping process
should now succeed.
*** OpenBSD 4.0 macppc: Segfault during dumping.
